Question

1 Select the correct option:

1. Moment of force about the given axis depends on
(a) distance of force from the axis
(b) distance of force from the axis only
(C) force and its perpendicular distance from axis
(d) magnitude of force alone

2. The moment of a force causes an object to
(a) move forward
(b) move backward
(c) stop moving
(d) turn about a fixed point

3. Two equal and oppositely directed forces acting on an object will be in equilibrium
(a) only if they act on the same point on the object
(b) if they are separated by a distance
(C) when they are balanced by a third force
(d) when their moments about the same point are equal

4. The pedals of a bicycle are placed at a large distance from the axle to
(a) ease the rotation by applying more force.
(b) ease the rotation by applying less force.
(c) make the bicycle look nice
(d) decrease the turning effect.
​

Answer 1

Answer:

Correct option is

D

both on the force and its perpendicular distance from the axis

Explanation:

We know that moment of force is given by formula r×F. Hence it depends on force and perpendicular distance from the axis.
